The soft flasks are particularly noteworthy, offering a convenient hydration solution that can be easily accessed on the go.

On the dorsal side, the X8 - 18L boasts a weather-resistant main compartment made of durable Cordura© Nylon 6.6 ripstop fabric.

The top and bottom horizontal stretch mesh pockets provide further organisational options, while the capability to carry a sleeping mat or tent underneath enhances its suitability for multi-day expeditions.

The X8 - 18L is available with or without the Instinct Hydra Cell 600ml soft flasks, giving you flexibility in terms of hydration solutions. This adaptability ensures that you can tailor the pack to your specific needs, whether you're embarking on a short trail run or a multi-day hike.
